Gears are a major part of every mechanical system and research methods aimed at gear fault analysis is an important sphere of research. A new direction in research in gear fault analysis can help better the existing trend. ANSYS simulation of gear faults has been rarely followed as a practice of helping to diagnose and analyse gear faults. This paper is purposeful in achieving the said task of using ANSYS.inc software to analyse the effects of various types of gear faults on the gears using finite element analysis.
